Chamfer Dimension and referance edge

In this model and drawing I have chamfer.  Question on how these are drawn and how this translates into a machined part.  If I select the vertical edge for the chamfer call out referance edge it gives me a .020x 35 degree but if i select the horizontal edge it give me .014 x 55 degrees.  If i didnt know any better, had not modeled this part and selected the horizontal edge as the referance would I get a different machined part.  Just curious. If so solidworks needs to know.  All are in 2011 sp2.  Thanks
